I'm sure there are people with this brand of coach who will advis. However the basic principle of winterizing is to bypass the fresh water tank wit the antifreeze and use the on board water pump to circulate the pink stuff through the pipis. If the valve does not cutoff the freshwater tank you fill it with antifreeze. If you don't turn it back on you get only air. If the tube has a cap you burn up your pump. I use the same tube not bypassed to fill the freshwater from a5 gallon container. Obviously something is preventing the water from flowing into the pump. It must be a valve in line between water tank and pump. Try this dip the antifreeze hose into bucket of water and turn on pump to see if water flows to a faucet or if you have alan antifreeze tank put water in and try the same thing.
